Risk factors for healthcare-associated infection in premature infants / 中国感染控制杂志

ABSTRACT

Objective To evaluate the occurrence and risk factors for healthcare-associated infection(HAI)in pre-mature infants.Methods The occurrence of HAI among premature infants who were born in a hospital from Janu-ary 2011 to June 2015 and admitted in the neonatal intensive care unit within 24 of birth were investigated prospec-tively,the related risk factors and intervention measures were analyzed.Results 644 premature infants were inves-tigated,32(4.97%)had HAI,the main infection site was lower respiratory tract (n=18,56.25%).34 pathogenic isolates causing HAI were detected, 24 (70.59%) were gram-negative bacteria, the major was Klebsiella pneumoniae (n=14);10 isolates were gram-positive bacteria(29.41%).Logistic regression analysis revealed that small for gestational age, low birth weight, severe amniotic fluid pollution, mechanical ventilation, feeding intolerance,indwelling gastric tube,irrational antimicrobial use,and long length of hospital stay were risk factors for HAI in premature infants (all P < 0.05).Conclusion Risk factors for HAI in premature infants are multiple, targeted interventions,such as shorten the length of hospital stay,reduce unnecessary invasive operation,use antimicrobial rationally,improve the feeding tolerance,are helpful for reducing the risk factors for HAI in premature infants.
